File Encryption and Decryption Using DNA Technology

Cryptography is the method of transforming the original texted message into an unknown form and in reverse also. It is the process of hiding and forwarding the data in an appropriate form so that only authorized persons can know and can process it. Cryptographic process secures the data from hijacking or transmutation, it is mainly used for users data security. This paper justifies the encryption and decryption using DNA(Deoxyribo Nucleic Acid) sequence. This process includes several intermediate steps, the perception of binary-coded form and generating of arbitrary keys is used to encrypt the message. A common key should be established between the sender and receiver for encryption and decryption process. The common key provides more security to the sequence. In this paper, both the process of binary-coded form and generating of arbitrary keys are used to encrypt the message. It is widely used in an institution and by every individual to hide their data from the muggers and hijackers and provides the data securely, and confidentially over the transmission of information.
